Figure 1 is a longitudinal vertical sectional view of my improved bolting-reel. Fig. 2 is an end view of the same, showing the upper half of the reel in vertical cross section. Fig. 3 is a sectional detail view of a portion of the covered frame of the reel. Fig. 4 is a similar view of a modification of the same. Fig. 5 is a detail plan view of a portion of one of the beater-blades. Figs. 6 and 7 are sectional views of the same, showing the manner in which the apertures in the beater-blades alternate. Figs. 8. 9, and 10 are respectively a plan view and two sectional views of a modi fication of the beater-blades, and Figs. 11, 12, and 13, and 14, 15, and 16, are likewise, each set of figures, a plan view and two sectional .views of two other modifications.

Similar letters of reference indicate corresponding parts in all the figures.

My invention has relation to centrifugal bolting-reels; and it consists in the improved construction and combination of parts of the frame and of the heaters, as hereinafter more fully described and claimed. 1

In the accompanying drawings, the letter A indicates the casing for the reel. B is the reel, which is mounted upon a shaft, (J, jourcogged rims of the reel, may have longer-cogs M, which will cause the reel to be jarred when pulley.

The frame of the reel consists a number of longitudinal strips, R, secured with their ends in the heads in zigzag shape, so that the surface of the reel will be serrated, and the spaces between the strips are covered by strips of bolting-cloth S, secured as shown in Fig. 3, the edges of the strips of cloth being clamped between the halves T T of the strips at the out-er points of the zigzag line. This construction will bring the faces U of boltingcloth at right angles to the direction in which the chop is thrown by the heaters, so that the chop will' be thrown squarely against the cloth, and in falling from the surfaces as the wheel revolves the chop will strike the other bolting-surfaces, V, so that the chop will be brought against two surfaces by being once thrown by the heaters. The chop will be still more divided than it was when it entered the reel by strik-' ing the two sides standing at an angle, and for the purpose of retaining the chop for a still longer time and carrying it up upon the upwardly-moving side, so as to drop it upon the naled in the casing, and which is provided heaters and again be thrown against the boltwith an inlet spout, D, opening into an annular aperture in one head of the reel, while the other end of the reel has an annular aperture which opens outinto adischarge-spout,E.

F is a discharge-screw, which is journaled, with its shaft G, in the lower end of the easing, and serves to convey the bolted flour to its discharge-chute H.

The heads of the reel are provided with smooth rims I, which travel upon balancingrollers J, journaled around the periphery of the rims, the said rollers supporting the reel and guiding it in its revolutions, and outside of these smooth rims the reel has two cogged rims, K, which mesh with pinions L upon the conveyer shaft, and these pinions, or the ing-surfaces, the surfacesV may be provided with longitudinal corrugations W, which will retain the chop and carry it upward upon the upwardly-n1oving side of the reel.

The heaters consistof longitudinal strips X, secured parallel in pairs upon the sides of the outer ends of the beater-arms Y, which project radially from the beater-shaft, and crossstrips Z,having their side edges bent upward, as shown at A, are secured at their ends upon these strips, either, as shown in Fig. 1, slightly inclined toward the discharge end of the reel, or straight, as shown in Fig. 5, the strips Z being secured upon thelongitudinal strips X, with spaces or apertures between them. These apertures alternate with strips upon the sev- IOC eral sets of longitudinal strips, so that where one blade has apertures the following beaterblade has cross-strips, and vice versa, so that if any chop. is drawn through the aperture of one blade it will meet a strip at the next blade and be thrown against the bolting-cloth. The outwardly-bent edges or flanges upon the crossstrips prevent the chop from sliding out and dropping over the sides of the strips into the spaces, and the construction shown in Figs. 8, 9, and 10 is substantially the same as the construction just described, with the exception that the cross-strips are integral with the longitudinal strips.

In the construction shown in Figs. 11, 12, and 13 transversely-corrugated strips are socured longitudinally upon the beater-arms, and the said corrugations are wide, and each raised portion of the corrugations has an aperture, the raised sides of the raised portions of the corrugations serving the same purpose as the flanges in the two formerly-described constructions.

In Figs. 14, 15, and 16 the strips are shown formed with a number-of small transverse corrugations and having the apertures in the same manner as the former constructions,and the fine corrugations will retain the chop and keep it from sliding laterally, while it at the same time will serve to comminute the chop as it falls upon the corrugations and is again thrown ofl from them. It will be seen that these beaters will throw all the chop against the bolting-surface, the chop falling through the apertures in one beater being caught and thrown by the cross-strips of the following beater. The conveyer-shaft, which revolves slower than the beatershaft, imparts a slow revolving motion to the reel by means of the pinions upon the convey er-shaft and the cogged rims upon the reel,and the reel will be shaken or jarred at intervals by the long cogs upon the pinions striking the cogged rims with which they mesh, the said shaking or jarring serving to loosen any chop which may have settled upon the bolting cloth. The chop enters the reel through the annular aperture in the head from the inlet-spout,and the bran and coarse particles of the chop pass out through the annular aperture in the other head and through the outlet-spout, while the bolted flour is collected in the bottom of the casing and carried to the outlet-chute bymeans of the screw-conveyor. By having the boltingsurface zigzag-shaped,or serrated, the surface in proportion to the radius of the bolt will be greater than by having the reel formed with a cylindrical or prismatical bolting-surface, and the chop will be thrown from one inclined surface to the other, thus subjecting it to more motion adapted to separate the finer particles from the coarser, and exposing different sides of the layer of chop thrown upon the boltingsurface.

Having thus described my invention, I claim and desire to secure by Letters Patent of the United States 1. The combination, with a bolting-reel, of a beater consisting of a shaft, radiating arms secured thereto, transversely-apertured beat er-blades secured to the outer ends of said arms and having their intermediate portions provided with bent edges, as and for the purpose set forth.

2. The combination, with a bolting-reel, of a beater consisting of a shaft, radiating-arms secured thereto, beater-blades secured to the outer ends of said arms, said blades being transversely apertured, and the intermediate portions having bent edges, and the apertures of one blade registering with the solid portions of the adjoining blade, as and for the purpose set forth.

3. The combination, with a bolting-reel, of a shaft, radiating arms secured thereto, and beater-blades secured to the outer ends of said arms, each of which blades consists of a series of cross-pieces secured at their ends to a pair'of longitudinal strips with spaces between them, said cross-pieces having flanged f. edges, as and for the purpose set forth.

4. The combination, with a bolting reel consisting of longitudinal bars secured in a zigzag line to the reel-heads, and the boltingcloth secured thereto, of a revolving beater consisting of transversely apertured beaten blades secured to the outer ends of radiating arms which are secured upon a shaft, as and for the purpose set forth.

5. In a bolting-reel, the combination of a reel having cogged rims upon its periphery, with a shaft receiving motion from the driveshaft, and having pinions provided at intervals with cogs longer than the others and meshing with the cogged rims, as and for the purpose shown and set forth.

6. In a boltingreel, the combination of a reel having circular flanges at its ends and cogged rims, guide-rollers journaled around the periphery of the flanges and having the flanges traveling upon them, and a shaft re ceiving motion from the beater-shaft and having at intervals cogs longer than the others and meshing with the cogged rims, as and for the purpose shown and set forth.

In testimony whereof I hereunto sign my name, in the presence of two subscribing witnes'ses, this 17th day of August, 1885.
